The USI AMIK3051SC 2-in-1 Sensing Plus® Smoke and Fire Alarm provides 10 years of continuous protection against deadly threats in the home. New Sensing Plus® Multi-Criteria Detection provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. Perfect for new or replacement installations, this USI Smoke Detector is suitable for houses, apartments and mobile homes. The sealed battery (included) will never have to be replaced throughout the life of the alarm, giving you a decade's worth in peace of mind even in the event of a power outage.

10 Year Permanent Power can also save you money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminate annoying low battery chirps and help the environment by reducing environmental waste from disposed batteries. This smoke and fire alarm features microprocessor intelligence that assists in completely eliminating nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the smoke detector's battery (approximately 10-years from activation).

Perfect for replacing existing USI Electric Smoke Detectors, this alarm features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the 10 year smoke and fire alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

Bring Your Home up to Code with 8th Generation Detectors

Exceeding industry standards and meeting the latest UL 217 8th Edition for smoke detection, this smoke and fire detector features approvals from the California State Fire Marshal and Federal Housing Authority (FHA) for ultimate peace of mind.

AMIK3051SC18 year battery smoke alarm
Many of our alarms come with a 10-year sealed Permanent Power battery that never needs replacing during the 10 year life of the alarm. Batteries in non sealed alarms should be replaced at least once a year or when the low battery signal sounds. Permanent Power battery technology helps keep you safe, because working smoke alarms are an important factor in surviving a home fire.
Early detection of smoke, carbon monoxide, and natural gas is key to saving lives. The National Fire Protection Association (NFPA) recommends installing a smoke alarm on every level of your home, including finished attics and basements. You are also encouraged to install a smoke detector inside every bedroom and at the top of certain stairways.
You never know what kind of hazard will strike your home, or when. That's why we recommend technology that can detect carbon monoxide (CO) and natural gas as well as smoke and fire. You'll get the most protection from devices that can quickly and accurately detect and respond to a range of threats.
A smoke alarm that goes off when there's no emergency is annoying. According to the National Fire Protection Association (NFPA), such "nuisance alarms" are the leading reason why homeowners intentionally disable their smoke detectors. Yet doing so can be deadly. A survey conducted by the NFPA found that smoke alarms sounded in only half of the home fires reported to U.S. fire departments, and almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.
Yes, all USI Sensing Plus Detectors meet new UL 217 8th Edition requirements for smoke alarms

So far so good!

Easy install. Steam from the kitchen will set it off occasionally, so we may need to move it away from the sink a little.

Do needed this Kitchen Smoke Alarm with special srnsors

We have three dogs and two of them are very sensitive to high-pitched sounds. With a basic Kidde Alarm we were constantly having to turn off the alarm and eventually remove it while baking or frying food. This alarm has only gone off once when I virtually broiled my garlic bread to a horrible black. Boy, can this alarm cook! And pups no longer terrorized throughout the evening meal prep. Love it.

No more false alarms

I purchased this unit for just outside my kitchen along with several other units for the rest of my house. My old detector was due to be replaced anyway but would also go off all the time when cooking from the heat when opening the oven door or the slightest amount of smoke. I put the new one to the test last night and no false alarms this time. Highly recommended.
